REVIEW Recent progress in understanding the molecular and cellular changes during tooth development and how they are mimicked during tissue repair, offers the opportunity to assess the biologic validity of the various vital pulp treatments. Under this light, indirect pulp treatment can be an acceptable procedure for primary teeth with reversible pulp inflammation, provided that this diagnosis i...

Magnesium sulphate has previously been shown therapeutic in porcine malignant hyperthermia. It was given intravenously in doses of 99 mg. kg -~ before and 277 mgkg -~ after an episode of malignant hyperthermia had been produced by halothane 1.5 per cent, in agroup of four malignant hyperthermia susceptible swine. Two groups of four additional MH susceptible and MH resistant swine received a con...

This study investigates the long-term (570 days) performance of alkali-activated slag (AAS) mortar exposed to combined wet-dry cycles and sodium sulphate solutions (i.e. 5 wt% 10 wt%). Physical mechanical characteristics AAS mortars visual appearance, compressive/flexural strength, mass change, capillary porosity, water sorptivity) as well mineralogical chemical parameters were determined using...

The accumulation of secondary acids and ammonium on individual mineral dust particles during ACEAsia has been measured with an online single-particle mass spectrometer, the ATOFMS. Changes in the amounts of sulphate, nitrate, and chloride mixed with dust particles correlate with air masses from different source regions. The uptake of secondary acids depended on the individual dust particle mine...

This study investigated the hydration characteristics and strength development of calcium sulfoaluminate-belite (CSAB) cements incorporating calcium carbonate (CC) powders with various particle size distributions and different gypsum amounts. In general, the CSAB hydration was accelerated by the CC powder, but the acceleration and resulting strength improvement were more effective with finer CC...
